' Specification of Letters Patent.

Patented Dec. 2, 1913.

Application filed October 23, 1912. Serial No. 727,471.

To all whom it may concern:

Be it known that I, FRIEDRICH ALTMANN, a subject of the German Emperor,and resident of Breslau, Germany, have invented certain new and usefulImprovements in Machines for Making Paper-Lined Pasteboard Boxes, ofwhich the following is a specification.

Hitherto, a machine for making paperlined paste-board boxes has becomeknown, in which previously cut lengths of pasteboard are singly ejectedfrom a container by a hand-operated slide onto a somewhat wider,stepwise movable paper ribbon, which is on its upper surface providedwith glue, and are then brought to below a press and combined thereinwith the paper ribbon carrying them, which at the same time is cut offby a knife, whereupon the projecting paper edge of the work-piece, whichis intended for lining the upper box edge, is turned over by ahand-operated tiltingledge, whereas all other work, namely thetransformation of the work-piece to a frame, the insertion of the bottomand the bending and pressing-on of the other paper edge, which isnecessary for fixing the latter, must be effected by hand. Certainly, itis not novel to perform the transformation and further formation of thepaste-board pieces, which are prepared on the known machine andconnected with the paper webs, on a ma chine, in which the web, of whichone paper edge must already have been turned over, is

brought between a winding bolt and a guiding roller located directlyabove the latter and from which the web is led around the bolt, while atthe same time a folding roller, which is connected with the guidingroller, places the projecting paper web edge over the edge of the boxbottom, which has already been previously pressed upon the face of thewinding bolt. In this machine, however, for turning over the web aroundthe winding bolt, besides the guiding roller a further winding cord,which is led over the latter and the bolt, is necessary, and eachfinished box must be removed from the bolt by hand. Besides, the twoknown machines cannot be so combinedthat the manufacture of the boxwould be possible in a continuous, uninterrupted way.

The resent invention provides a machine, by .WlllCll paper-linedpaste-board boxes of previously cut lengths of paste-board can beautomatically made in a continuous, uninterrupted way and the finishedboxes also be automatically ejected.

According to the invention, the paper ribbon and the front,non-supported end of the paste-board length, which is located at acertain distance above the paper ribbon and periodically supplied, arecaught by a pair of known periodically disengageable conveying rollersand are glued together during their advance, while the projecting edgeof the paper web, which has meanwhile been cut off from. the ribbon, isfirst bent by an inclined ledge, whereupon the whole workpiece, whileadvancing, passes beneath a winding bolt, which is narrower than thepaste-board length, where it is caught by a rotary clamping member andled around the bolt, while at the same time also the other projectingpaper edge, which serves for fixing the bottom of the box is turned overby known folding rollers upon the bottom, which has previously beenpressed upon the face of the winding bolt. Furthermore, in the extensionof the winding bolt a piston and a shell inclosing same are movablylocated on a common axle and adapted to be moved successively toward thewinding bolt and back by means of a pair of camoperated levers, so thatthe piston places the paper edge, which has first been bent by theledge, around the inner box edge, while at the same time a verticallymovable molding-roller, which is located beneath the winding bolt,smoothens the outer box envelop and the shell, which is movable on thepiston, ejects by its now following forward movement the finished boxfrom the winding bolt.

Periodically disengageable conveying rollers for conveying work-piecesare, of course, not new per 86 but according to the invention they donot only serve for advancing a work-piece but, further, for combiningthe two parts of the work-piece and at the same time for assisting inthe further formation or transformation of one part, that is they areused for a purpose hitherto not known in the art.

The accompanying drawing shows the improved machine.

Figure 1 is a plan view of the same, Fig. 2 a front view omitting thecontainer for the paste-board pieces, Fig. 3 a side view of part ofsame, Fig. 4 a fragmentary sectional side view on the line BB of Fig. 1,Fig. 5 a plan View, partly in section, of the container for thepaste-board pieces with cutting-off device and clamping means for thepaper web, Fig. 6 a front view of the latter arrangement, and Figs. 7and 8 sections on the lines CG and DD of Fig. 6 respectively.

The paper web 1 (Fig. 4) arrives from a paper roll and is led over aroller 2, which rotates in glue, its free end being before commencementof the operation introduced by hand into the race 3 of the machine.Beside the latter, a container 5 (Figs; 5 and 6) is fixed and filledwith superposed paste-board pieces 4, a slot being provided on eachlongitudinal side of same directly above its bottom, so that by means ofa slide 11, which is connected with levers 6, 7, 8 (Fig. l) andcontrolled by a cam disk 10 on an axle 9 one paste-board piece can beejected from the container 5 upon each stroke of the slide until itabuts against a lateral boundary abutment-ledge 12 of the race 3.Thereby, the paste-board piece is put upon a number of horizontaltongues 13 attached to the bottom of the container and provided withclamp-springs 13 and which serve to keep the same apart from thesomewhat wider paper web. In this position, the non-supported projectingend of the ejecting paste-board piece is disposed beneath a roller 14,which is located on an angle-lever 15 (Figs. 1 and 4) which is loaded bya weight 15 and controlled by a cam disk 16 on the axle 9, so that itcan be alternately lowered and again be raised by action of said lever.The end of the paper web in the race 3 is carried by cross-ledges 17(Fig. 5) and supported in the vertical plane of roller 14 by a roller19, which can be driven from a toothed gearing 18 Upon the roller 14being lowered by action of the cam disk 16, it presses that part of thepaste-board piece, with which it comes in contact, upon that part of thepaper web, which rests upon the roller 19, whereby, owing to the paperweb being provided with glue on its upper surface, the contact pointsare glued together, while the toothed gearing 18" is put in gear, sothat the two connect'ed pieces are advanced and thereby glued togetheron their whole length. Meanwhile, the cam disk 16, during its furtherrotation, turns the lever 15 in such a way that the roller 14 is againlifted by the same, whereby the movement of the paper ribbon is stopped.At this moment, a knife 24, which swings on spring bolt 23 and which isacted upon by levers 21, 22 which are controlled from a cam disk 20, isoperated in such a way known in the art that it cuts the paper web off,somewhat behind the paste-board piece connected therewith. In order toprevent, during this action, a back ward displacement of the free end ofthe paper ribbon, which lies then loosely in the race 3, the operatinglever 22 of the knife is connected with a double-armed lever 26, whichis fulcrumed 25 and the front arm of which presses with its angularlybent horizontal end 26 on the free end of the paper ribbon at the momentof the cutting operation and thus prevents the same from slipping back.Upon the two parts of the work-piece being connected and moved forward,one projecting edge of the paper web, which serves for lining the upperbox edge, strikes against a lateral ledge 27 5) in the race, which bendsthe same angularly. Thus prepared, the workpiece passes beneath awinding bolt 28, on the face wall of which a box bottom, which is takenfrom the container 29, has meanwhile been placed and secured in a wayknown in the art. At this moment, the front end of the workpiece iscaught by a clamping member 30 (Fig. 2), which rotates with the windingbolt 28 and which is periodically disengageable, and wound around thebolt, while the other projecting edge of the paper web, which serves forfixing the bottom, is placed upon thebottom edge by folding rollers 31(Fig. 4) known in the art.

The clamping member 30 receives its movement from a double-armed lever32 connected therewith and fulcrumed on the end of a member 35, which isfixed on a toothed wheel 33 and movable on the axle 34 and provided withan angular arm 35*. The front arm of the double-armed lever 32 isconnected with the arm 35 by a tensioned spiral spring 36, while the endof its rear arm is disposed in the vertical plane of a ring segment 37.The toothed wheel 33, is connected with the member 38, which is moved toand fro by action of a lever which is controlled by a cam disk 39, whereby the member 35 on the double-armed lever 32 is alternately moved inopposite directions on the axle 34. By the tendency of the tensionedspring 36 to approach the front arm of the double-armed lever 32 to thearm 35, the clamping member 30 is pressed against the winding bolt 28,where by it catches the front end of the advancing work-piece. As thelever 32 is then turned on the axle 34, the clamping member 30 re mainson its pressure place and rotates with the winding-bolt, it placing thework-piece, which is guided on the ledge 17 around the bolt. At the sametime, the rear end of the double-armed lever 32 moves around, the ringsegment 37 until it slides down from the same and finds its abutment ona gripper-like finger 41 connected with the segment axle 38 (Fig. 3). Atthis moment, the segment 38 passes into its backward movement and causesthereby also the movement of the double-armed lever 32 in oppositedirection the rear arm of same being by the finger 41 pressed below thesegment ring, on the lower surface'of which it moves then back, so thatthe clamping member 30 is raised from the winding bolt, until the leverarm, at the end of its backward movement passes from below the other endof the segment ring and by action of spring 36 outward so that theclamping member 30 can catch the next work-piece and place the samearound the bolt at the following forward movement of the lever 32. Uponthe work-piece being-wound on the windingbolt and the bottom gluedthereto by the folding rollers 31 (Fig. 4), a piston 43, which islocated beside the winding bolt 28 and movable on the axle 42 of same,is moved toward the bolt by action of a doublearmed lever 45 which iscontrolled by a cam disk 44, the piston pressing then the previouslybent paper edge onto the inner edge of the box, while at the same time avertically movable pressure-roller 46, which is located below thewinding roller and shaped corresponding to the form of the box, andwhich may also be fitted with printing types for printing on the name ofthe firm or the like, smoothens the box envelop. This process beingfinished, immediately after lowering of the roller 46 a shell 47inclosing the piston 43 moves toward the bolt by action of adouble-armed lever 49, which is controlled by a cam disk 48, and ejectsthe finished box.

The putting of the box bottom on the face of the winding bolt iseffected in a way known in the art during the time, in which the roller14 combines the parts of the work-piece and moves same toward thewinding roll, the bottoms being stored in a container 29 beside andabove the winding bolt, from which they are periodically ejected bylevers, which are controlled by a cam disk, the bottoms being then ledto a pair of tongs 50, which bring same by action of an eccentric intovertical position and place them on the face of the winding bolt, wherethey are held by the head 34" of the movable axle 34, which iscontrolled by cam disk 52, until the projecting paper web of thework-piece has been placed around the edge of the bottom by action ofthe folding rollers 31.

I claim:

1. In an automatic machine for making paper-lined paste-board boxes, thecombination of a pair of periodically disengageable conveying rollersdesigned to catch the paper lining and the front end of a pasteboardpiece and to press them together on their forward movement, an inclinedledge to first bend the projecting edge of the paper web which is toline the upper box edge, a winding bolt of narrower width than thepaste-board piece, a clamping member to lead the workpiece around thewinding bolt, folding-rollers to turn the other proj ecting edge of thepaper web upon the bottom of the box which has been pressed upon theface of the winding -roll, a movable piston and a shell inclosing samearranged in the extension of the winding bolt, a common axle for thepiston and shell, levers to move the latter alternately toward the winding bolt and back and to allow the piston to place the previously bentprojecting edge of the paper web around the inner box edge, and avertically movable molding roller beneath the winding bolt to smoothenthe outer box envelop, all for the purpose set forth.

2. In an automatic machine for making paper-lined paste-board boxes, incombination a winding bolt, a clamping member to wind the work-piece onthe same, a doublearmed lever to carry said clamping member, a toothedwheel on the fulcrum of the lever adapted to be moved alternately to andfro, and a tensioned spring as well as a ring segment to control saidlever and to cause same to alternately press the clamping member uponthe bolt, in order to rotate with the same, or to lift it away therefromto start for the engagement of the next workpiece.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
